TANK- CLOSURE.

Application led May 10,

To all whom t may concern:

Be it known that I, VERGNE A. NIKON, a citizen of the United States, residing at Lake Villa, in the county of Lake and State of Illinois, have invented new and useful Improvements in Tank-Closures, of which the following is a specification.

The device which is the subject matter of the present application for patent has been designed more particularly to serve as a closure for the filler opening of gasoline tanks Carried by motor vehicles, although it is not limited to such tanks, but may be applied, with equal facility, to other tanks or receptacles.

The invention has for its object to rovide a novel and improved closure w ich quickly manipulated for removal from the filler opening, and for application thereto, and to this end the invention consists in a combination and arrangement of parts to be hereinafter described and clalmed.

In order that the inventionl may be better understood, reference is had to the accompanying drawing forming a part of this specification, and in said drawingf Figure 1 is a plan view of the device; 4 gigs. 2 and 3 areside elevations thereof, an l Fig. 4c is a cross section of the device in place.

Referring specifically to the drawing, 5 denotes a fragment of a tankor other receptacle having a. `filler opening 6 which is screw-threaded to seat a closure in the form of a screw plu 7. In order that the tank may be filled without removal of the plug 7 from the opening 6, the plug has'a large central pouring opening 8 from the top to the bottom, andthis opening is provlded with a closureconsisting of a disk 9 adapted to enter the opening to seat on a shoulder 10 therein. The 'under side ofthe disk 9*,where it seats on the shoulder10may,be .provided with a suitable gas Yet 11 to form aliquidtight seal.

Through the center of the disk 9 passes a I pin 12 carrying at itsy upper end a cross bar 13, and having below the disk a cotter pin or other suitable abutment 14. The pin-12 passesloosely through the disk 9 so that the Specification of Letters Patent. i

, pressed down said member at the outer Patented Feb. 22, 1921. 1920. serial No. 380,258.

latter is not disturbed when the cross bar 13 is swung and the pin turns.

Between the top of the disk 9 and the under side of the cross bar 13, a spring 15 is coiled around the pin 12. This spring -acts to hold the disk .9 pressed down to its seat 10. j

'The topbf the plug 7 has two diametrically opposite, upstanding flanges 16, each of which has its top edge inclined, as shown at 17, the two inclines running in opposite directions. The end of each fiange 16 at the highest point of the incline 17 isshaped to form an overhanging hook 18. p

The cross bar 13 is reduced at its ends as shown at 19, and said ends are adapted to seat under keeper mem-ber consistin lof the, hooked ends 18 ofthe flanges 16, and4 spaced from the tp of the plug 7. It will thereforevbe seen .that when the cross bar 13 is and given a slight turn to clear the hooks 18, the closure disk 9Ymay be removed from the opening 8 ,in the pl g 7. Upon turning the cross bar after it clears the hooks, it ,will climb'the inclines'l7, and this upward movement ofthe cross bar lifts the disk off itsseat 10.' To again apply the ldisk 9 the actionvjust described is reversed, the cross bar being swungl to travel down the inclines, and untll its ends 19 again seat underthe hooks 18, the inclines guide said ends to the hooks.

I claim:

1. A' member having a filler opening and diametrically opposite flanges rising from end of the opening, .said ianges having their top edges inclined in opposite directions, and the ends of the flanges ,at the top of the inclines-having overhanging hooks, a cross bar adapted to seat at its ends under the hooks, a closure 2. A. closure for the iiller opening of a rel ceptacle, said. closure comprising a plug seating in said opening and having a pouring opening, vand provided with diametrically'opposit'e fianges rising from the plug at the outer end of the pouring opening,

said flanges having their top edges inclined bar and Ahawing a loose connection with the in opposite. directions, and the ends of the closure, and a spring interposed between flanges at the top of the inolines having the closure andthe crossbar forholding the 1ov overhanging keeper lmembers, a cross bar former seated.
